Question

how do i simplify (8a)^2

Answer 1

(8a)^2 = (8^2)(a^2)

Answer 2

(8a)^(2) = (8a)(8a)

Answer 3

Please explain

Answer 4

\[x^2 = (x)(x)\]

\[x^3 = (x)(x)(x)\]

etc

thus

\[(xa)^2 = (xa)(xa)\]

Answer 5

Ok Thanks

Answer 6

do you follow now?

Answer 7

(8a)^-2

Answer 8

how did you get that

Answer 9

Thats the actually question simplify (8a)^-2

Answer 10

with exponents you combine like terms

\[(2x)^3 = (2)(2)(2)(x)(x)(x) = 4(2)(x)(x)(x) = 8(x)(x)(x) = 8x^3\]

Answer 11

Ok I got it

Answer 12

\[(8a)^{2} \neq (8a)^{-2}\]
\[(8a)^{-2} = \frac{1}{(8a)^{2}}\]

Answer 13

just a note so you understand negative exponents

Answer 14

\[x^{-1} = \frac{1}{x^{1}} = \frac{1}{x}\]
