Question

Compare √42 and √58 plotted on the number line. What is the approximate difference in tenths between the two values?

Answer 1

1.2

Explanation:

You must find the square root of both numbers, 42 and 58, then subtract them.

The square root of 42 is 6.48074069841, or in this case, 6.4

The square root of 58 is 7.61577310586, or in this case, 7.6

Subtract 7.6 - 6.4 = 1.2

Answer 2

Judging by the question I noticed that you simply have to input both of these roots into a calculator and subtract the smaller one from the larger one.

After putting both into a calculator I got these results
√42= ~6.4807 and √58= ~7.6158

I next subtracted the smaller sum from the larger one and got ~1.1351 as my value, and to answer your question it would be 1.1 to the nearest tenth.
