What is 15+ ^2 ( 4 -2 ⁻¹ 3 ) equal to?

Step-by-step solution

aligned 2 ⁻¹ 3 & =2 ⁻¹ 1 3 = ⁻¹ 2 3 1- 1 9 & = ⁻¹ ( 2 3 9 8 )= ⁻¹ 3 4 aligned So, aligned 15+ ^2 ( 4 . - & .2 ⁻¹ 3 ) & = 15+ ^2 ( ⁻¹ 1- ⁻¹ 3 4 ) & = 15+ ^2 ( ⁻¹ ( .1- 3 4 ) 1+ 3 4 ) ] & = 15+ ^2 ( ⁻¹ 1 7 ) & = 15+7^2 & = 15+ ^2 ( ⁻¹ 7 ) & = 15+49 =8 aligned
