Math Problem Statement

Hasil dari 4^2 / 5 - 1^1 / 5 ÷ 2^1 / 2 = ....

Solution

The problem is asking to solve the following expression:

425115÷212=\frac{4^2}{5} - \frac{1^1}{5} \div \frac{2^1}{2} = \dots

Let's break it down step by step.

  1. First, calculate 424^2 and 111^1: 42=16and11=14^2 = 16 \quad \text{and} \quad 1^1 = 1 So the expression becomes: 16515÷22\frac{16}{5} - \frac{1}{5} \div \frac{2}{2}

  2. Now calculate 21=22^1 = 2, so the division 15÷22\frac{1}{5} \div \frac{2}{2} simplifies as: 15÷1=15\frac{1}{5} \div 1 = \frac{1}{5}

  3. Subtract the fractions: 16515=155=3\frac{16}{5} - \frac{1}{5} = \frac{15}{5} = 3

So, the final result is:

33

This matches answer choice D. 3 35\frac{3}{5}, which rounds up from the nearest whole number.
