705,003 is seven hundred five thousand, three in standard form
Three miles a day should be the correct answer
The correct answer is (-3,1)
1 pound of coffee costs 6.95
3.4 pounds will cost 6.95 x 3.4 = 23.63
They want you to write the number in index form.
The number is 5N^2, where N = 3 x 5^2 x x^3
So:
5N^2 = 5 x (3 x 5^2 x x^3)^2
= 5 x (3^2 x 5^4 x x^6)
= 3^2 x 5^5 x x^6
or a bit neater looking: 3² ₓ 5⁵ ₓ x⁶
