Standard form
15 million = 1.5 × 10 (to the power of 7)
That I get.
Q is.: write the following as standard form
0.005 × 10 (to the power of 3)
5
0.005 x 10^3 = 0.005 x 1000 = 5 or 5 x 10^0 if they particularly want it in that form.
I thank you. I thought the same but didn' think 10^0 could be a thing.
x^0 = 1 for all values of x, FWIW.
Anything^0 is 1 (I think, except 0 which breaks the matrix so please don’t actually type that.)
I read that question differently and would say the answer is 5 × 10^-3 The question is asking to rewrite the expression in standard form. But that surely isn't gcse is it?
except 0 which breaks the matrix
Nope, still 1 🙂
5 × 10^-3 is 0.003 surely?
5x10^0
5 × 10^-3 is 0.003 surely?
No, it's 0.005.
10^-3 = 0.001
3 * 10^-3 = 0.003
5 * 10^-3 = 0.005
But the question is about 0.005 * 10^3 = 5 * 10^-3 * 10^3 = 5 * 10^0 = 5 🙂
Yes, stop all this chat about 0.005.
0.003 is even worse. Zippit!
