Step-by-step explanation:

$(26) \\ \frac{m}{3} - 4 \geqslant \frac{m - 2}{4} \\ \\ \therefore \: \frac{m - 12}{3} \geqslant \frac{m - 2}{4} \\ \\ \therefore \:\frac{4(m - 12)}{12} \geqslant \frac{3(m - 2)}{12} \\ \\ \therefore \:4m - 48 \geqslant 3m - 6 \\ \\ \therefore \:4m - 3m \geqslant 48 - 6 \\ \\ \huge \red{ \boxed{\therefore \:m \geqslant 42}} \\ \\ (27) \\ \frac{a}{2} - \frac{a - 3}{3} < 5 - \frac{a}{6} \\ \\ \therefore \: \frac{3a - 2a + 6}{6} < \frac{30 - a}{6} \\ \\ \therefore \: \frac{a + 6}{6} < \frac{30 - a}{6} \\ \\ \therefore \: a + 6 < 30 - a \\ \\ \therefore \: a + a < 30 - 6 \\ \\ \therefore \: 2 a < 24 \\ \\ \therefore \: a < \frac{24}{2} \\ \\ \huge \orange{ \boxed{\therefore \: a < 12}}$

Why is 3^7 equal to 7 1/3

The required answer is $(7^{\frac{1}{3}})^{3} = (7^{\frac{1}{3}*3}) = 7^1=7$ .

<u>what is a power rule for exponents ?</u>

$(a^m)^n=a^{mn}$ is known as the power rule for exponents. Exponent times power is how you raise a number with an exponent to a power.

A number's exponent demonstrates how many times we are multiplying a given number by itself. 3^4, for instance, indicates that we are multiplying 3 by four. 3*3*3*3 is its expanded form. The power of a number is another name for an exponent. It could be an integer, a fraction, a negative integer, or a decimal.

$(7^{\frac{1}{3}})^{3} = (7^{\frac{1}{3}*3}) = 7^1=7$

Here, we have used the rule $(a^m)^n=a^{mn}$

Five times the sum of the digits of a two-digit number is 13 less than the original number. If you reverse the digits in the two

mafiozo [28]

Answer:

The difference of the original two-digit number and the number with reversed digits is 18.

Step-by-step explanation:

Since it's a two digit number, let x represent the tens digit and let y represent the units digit.

Thus, the original two digit number is;

10x + y.

The reverse two digit number is;

10y + x.

We are told that five times the sum of the digits of the two-digit number is 13 less than the original number.

Thus;

5(x + y) = (10x + y) - 13

Multiplying out the bracket gives;

5x + 5y = 10x + y - 13

Rearranging gives;

10x - 5x + y - 5y = 13

5x - 4y = 13 - - - - (3)

Also,we are told that, four times the sum of its two digits is 21 less than the reversed two-digit number. Thus;

4(x + y) = (10y + x) - 21 - - - (4)

Simplifying gives;

4x + 4y = 10y + x - 21

>> 10y - 4y - 4x + x = 21

>> 6y - 3x = 21 - - - (4)

Solving eq(3) and (4) simultaneously gives;

x = 5 and y = 3

Thus,

Original number = 53

Reversed number = 35

Difference between original and reversed number = 53 - 35 = 18
