Question

Simplify the following

1.) (a+b)^2
2.) pq+8x+2pq+x^2
3.) (4pq/2pq)^2
4.)4^16÷4^4
5.)5x=1/25​

Answer 1

(a+b)^2 = a^2 + 2ab + b^2pq + 8x + 2pq + x^2 = x^2 + 3pq + 8x(4pq/2pq)^2 = (2)^2 = 44^16 ÷ 4^4 = 4^12 = 16,777,216To solve for x, we can start by isolating x on one side of the equation:

5x = 1/25

x = (1/25) ÷ 5

x = 1/125
