40y-1 ,y=5
(40 * 5) -1 = 199
1/40y(with exponent 1) =1/40(1)(with exponent 1) = 200

To find the value of the expression 40y - 1 when y is equal to 5, we substitute y = 5 into the expression and perform the calculation.
Step 1: Substitute y = 5 into the expression.
40y - 1 = 40(5) - 1
Step 2: Simplify the expression by performing the arithmetic operations.
40(5) - 1 = 200 - 1
= 199
Therefore, when y is equal to 5, the value of the expression 40y - 1 is 199.
