Which expression is the same as 6 times 52?

A) 2(50 + 6)
B) 6(50 + 2)
C) 6(5 + 2)
D) 50(6 + 2)

B

Step-by-step explanation:

6 times 50 = 300

6 times 2 = 12

300 + 12 = 312

6 times 52 = 312

B

Step-by-step explanation:

6 times 52 = 6*52 = 6*(50+2)

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:
