Find the roots and simplify the expression. 216^1/3 - 125^1/3​

Mathematics
1 answer:
Gelneren [198K]3 years ago
4 0

Answer:

1

Step-by-step explanation:

The first thing to simplify is the Exponent

If The Exponent is a fraction than the denominator of the fraction will be the power of the root and the numerator will be the power of the expression

It will be in the form

\sqrt[a]{ {x}^{b} }

Where a is the denominator and b is the numerator of the fraction

The first expression 216^1/3 will be

\sqrt[3]{{216}^{1} }

6×6×6=216 so the expression = 6

The second expression 125^1/3 will be

\sqrt[3]{ {125}^{1} }

5×5×5=125 so the expression =5

216^1/3 - 125^1/3

6 - 5

43×15= what is the correct answer
mario62 [17]
43 × 15 = 645.

First, set up the long multiplication.
Second, calculate 3 × 5, which is 15. Since 15 is two-digit, carry the first digit 1 to the next column.
Third, calculate 4 × 5 which is 20. Since 21 is two-digit, carry the first digit 2 to the next column.
Fourth, bring down the carry digit of 2. 
Fifth, calculate 3 × 1, which is 3.
Sixth, calculate 4 × 1, which is 4.
Seventh, calculate 215 + 430, which is 645.
Eighth, therefore, 43 × 15 = 645.

Or.. an easier way is to use a calculator. They always come in handy when doing multiplication.

QUICK HELP!!!!
sasho [114]

Answer:

y =  \frac{3}{4} x -  \frac{3}{2}

Step-by-step explanation:

y =  \frac{3}{4} x - 1→y - y1 = m( x - x1)

y - 6 =  \frac{3}{4} (x - 6)→y - 6 =  \frac{3}{4} x - 6

2(y - 6) = 2( \frac{3}{4} )(x - 6)

2y - 6=  \frac{3}{2}( x - 6)

2y - 6 =  \frac{3}{2} x - 9

- 6 \: from \: both \: sides

2y  =  \frac{3}{2} x - 3

divede \: by \: 2 \: on \: both \: sides

y =  \frac{3}{4} x -  \frac{3}{2}

Hope this helps!
