Solution: (x+3) 2 = 36

X+3=(+-)6

X=(+-)6-3

So X 1=3 X2=-9.

3(2X- 1)^3+25= 1

Solution: 3 (2x- 1) 3 =-24.

(2X- 1)^3=-8

2X- 1=-2

2X=- 1

X=- 1/2

To do this topic, we must first understand some formulas.

A 0 = 1 (A not =0)

A (- 1) = 1/a (A is not equal to 0)

√( 16)-(-3)+(π -3. 14)^0-( 1/3)^(- 1)

=4+3+ 1-3

=5
