Following the order of operations, we need to start with the power.
132.06÷(4^2+2.6) → 132.06÷( 16+2.6)
Now, we will calculate the addition inside the parentheses. To add decimals, we line up the decimal points so that place-value positions correspond. Annex a zero so that each place has a digit.
Now we add the decimals, just as we would with whole numbers, and place the decimal point in the answer.
The sum of the given numbers is 18.6. Now, let's substitute these result into the given expression.
132.06 Ă· 18.6
The next step is perform the division. The calculations are easier if we multiply the divisor and the dividend by the same power of 10 so that the divisor is a whole number. In this case, we will multiply by 100.
132.06* 100 &=13206
18.6* 100 &= 1860
This means that 132.06Ă· 18.6 is the same as 13206Ă· 1860. Now we will find the quotient. We divide, multiply, subtract, and compare as many times as we need.
Since 13206Ă· 1860=7.1, we know that 132.06Ă· 18.6=7.1.
