Type the correct answer in the box. Use numerals instead of words. Consider this expression. |m^2 - 7| + n^2

When m = -2 and n = 5, the value of the expression is [?]

I answered 36, but it says I am wrong. Is this the correct answer? Or is it something else?

The value of the expression is 28.

Step-by-step explanation:

Given that m = -2, and n = 5:

=

= | 4 - 7 | + 25

= | -3 | + 25

= 28

Let me know if you have any questions :)

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
