Answer:

$\log_8(64) = 2$

Step-by-step explanation:

We are given an equation:

$8^2 = 64$

We have to convert this into a logarithmic equation.

We know that:

$b^x = a$

where b is the base and x is the exponent.

Then, it can be written as:

$\log_b(a) = x$

So, we have b = 8, x = 2 and a = 64

Thus, we can write:

$\bold{\log_8(64) = 2}$

It is the required logarithmic equation.

㏑(8^2) = ㏑(64)
or
㏑(a^n) = n㏑(a)
so
2㏑(8) = ㏑(64)

Is it what you mean by logarithmic equation ?

Hi there!

${x}^{2} \times {x}^{5} = x {}^{2 + 5} = {x}^{7}$

We can also write is out entirely.
${x}^{2} = x \times x$
${x}^{5} = x \times x \times x \times x \times x$
${x}^{2} \times {x}^{5} = \\ (x \times x ) \times (x \times x \times x \times x \times x) = \\ x \times x \times x \times x \times x \times x \times x = \\ {x}^{7}$

Cara evaluated the expression below. (4(7-13))÷3+(-4)²-2(6-2) =(28-13)÷3+(-4)²-2(4) =15÷3+16-8 =5+16-8 =13 What was Cara’s error

Answer:

the answer is the first one, Cara multiplied only 4 and 7 together and did not multiply 4 and 13

Step-by-step explanation:

if you look through the question you can see that Cara evaluated the (-4)^2 correctly because a negative multiplied by a negative gives you a positive thus (-4)*(-4)= 16, then next you can see that Cara subtracted 2 from 6 correctly because (6-2)= (4), and last but not least Cara did multiply 2 by 4 correctly because 2*4 or 2(4) =8 so as you can see the answer is the first one
