olga_2 [115]

Answer:

The correct options are A ,C and F.

Step-by-step explanation:

The given expression is

$81^x$

Calculate the simplified form of given options.

$(9\cdot 9)^x=81^x$

$9\cdot 9^{2x}=9\cdot (9^2)^x=9(81)^x$

$9^x\cdot 9^x=(9\cdot 9)^x=81^x$

$9^2\cdot 9^x=81(9^x)$

$9\cdot 9^x=9(9^x)$

$9^{2x}=(9^2)^x=81^x$

Therefore correct options are A ,C and F.

Which value for x would make the statement true? -8x = -32

Zigmanuir [339]

Step-by-step explanation:

Hey there!

Given;

-8x= -32

~ Divide both sides by"-8".

(-8x)/-8 = (-32)/-(8)

Or, X= 4.

Therefore, the value of x must be 4.

Check:

-8*4 = -32

-32 = -32 (True)

Hope it helps...
