Question

Solve b and please help me fast

Answer 1

(2/3)² ×(2/5)-³ × (3/2)²

here taking the reciprocal of the second term we have

(2/3)² × (5/2)³ × (3/2)²

2²/3²  ×  5³/2³  × 3² / 2²

WE KNOW BY TWO FORMULAS THAT

APOWER M × A POWER N = APOWER M PLUS  N

APOWER M ÷ A POWER N = A POWER M - N

BASED ON THESE FORMULAS WE HAVE THE EQUATION

2 POWER  2-3 × 5 POWER 3-2 × 3 POWER 2-2

2 POWER -1 × 5 POWER 1 × 3 POWER 0

WE KNOW THAT 3 POWER O = 1

1/2 × 5 × 0

0.

HENCE THE ANSWER IS O.
