Does anyone know the answer please

A, B, C are false. D, E, F are true

Step-by-step explanation:

let's use the number 3 as a case study

A. 3²-1 = 9 - 1 = 8 (false)

B. 3(3-1) = 3 × 2 = 6 (false)

C. (3-1)² = 2² = 4 (false)

D. 3² + 2 = 9 + 2 = 11 (true)

E. 3(3-2) = 3 × 1 = 3 (true)

F. (3-2)² = 1² = 1 (true)

i dont know sorry

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:
