Use the given information to classify jk for j (a, b) and k (c, d)
a) a=c
b) b=d
c) a=b and c=d

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

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:
