Question

Evaluate 23x-1 for x = 1. 1 4 7 8

Answer 1

THE ANSWER IS 8 :)

Step 1: Simplify. Turn 2^3x-1 into 2^3(1)

Step 2: Multiply exponents. 3 times 1 is 3 so it simply becomes 2^3

Step 3: Solve. Multiply 2 by itself three times. By doing this, you get 8!

2x2x2=8

Answer 2

replace the value of x int eh equation

so 23x-1 becomes

23(1.1478)-1

23*1.1478 = 26.3994-1 = 25.3994
