Question

18×2^-4=???????????????????

Answer 1

$18*2^{-4}=18*\frac{1}{2^{4}}=18*\frac{1}{16}=9*\frac{1}{8}=\frac{9}{8}=1\frac{1}{8}$

Answer 2

To calculate the expression, let's first simplify it step by step:

1. 18 × 2^(-4)

Since 2^(-4) means 1 divided by 2^4 (which is 16), we have:

2^(-4) = 1/16

Now, substitute 2^(-4) back into the original expression:

18 × 1/16

To multiply a number by a fraction, you can multiply the number by the numerator and then divide the result by the denominator:

18 × 1 = 18 18 ÷ 16 = 1.125

So, 18 × 2^(-4) is equal to 1.125.
