Im not sure what to do plz plz plz and look at pic.

It going to be 48 cuz tour justo multiplying

[(2^3)^3]^2 = x

Here, you just begin solving from what's in the first bracket, which is 2^3.

Step 1, solve what's in first parentheses:
 [(2^3)^3]^2 = [(2 x 2 x 2)^3]^2 =[(8)^3]^2
Step 2, solve what's in the second parentheses:
[8^3]^2 = [8 x 8 x 8]^2 = [512]^2
Step 3, now you solve the equation by following PEMDAS 9you are done with the parentheses):
512^2 = 512 x 512 = 262,144

[(2^3)^3]^2 = 262,144
