replace the value of x int eh equation
so 23x-1 becomes
23(1.1478)-1
23*1.1478 = 26.3994-1 = 25.3994
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
