(4 x 10 ^ 7) ÷ (8 x 10 ^ 4) in standard form Plz answer

500

Step-by-step explanation:

( 4 x 10^7 ) ÷ ( 8 x 10^4 )

= ( 4 x 10^4 ) ( 10^3 ) ÷ ( 4 x 10^4 ) x 2

= 10^3 ÷ 2

= 1000 ÷ 2

= 500

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:
