Final answer:
To work out the division (1.8 x 10) ÷ (3 x 10) in standard index form, divide the numbers and subtract the exponents.
Step-by-step explanation:
To work out (1.8 x 10) ÷ (3 x 10) in standard index form, we divide the numbers and subtract the exponents. 1.8 ÷ 3 = 0.6 and 10 ÷ 10 = 1. Therefore, the answer is 0.6 x 10-1. The exponent in the standard index form represents the number of times the base (10) is multiplied by itself, which in this case is once.
