Question

From the following E to the power of ring operator values of half cells,

i) straight A to the power of 3 minus end exponent not stretchy ⟶ straight A to the power of negative 2 end exponent plus straight e semicolon straight E to the power of ring operator equals 1.5 straight V

ii) straight B to the power of plus plus straight e not stretchy ⟶ straight B semicolon straight E to the power of ring operator equals 0.5 straight V

iii) straight C to the power of 2 plus end exponent plus straight e not stretchy rightwards arrow straight C to the power of plus semicolon straight E to the power of ring operator equals 0.5 straight V

iv) straight D not stretchy rightwards arrow straight D to the power of 2 plus end exponent plus 2 straight e semicolon straight E to the power of ring operator equals negative 1.15 straight V
