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
First, fill in the blanks.
1 and+16 are pronounced as (),-as ().
