Prove: The square of the sum of two consecutive integers is odd.
(n + (n + 1))2 = ([ ? ]n + 1)2
= [ ]n2 + [ ]n + [ ]
= 2 ]n2 + [ ]n) + 1
= odd

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

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:
