The first number in this item can be also expressed as 2.3 x 10³. Now, dividing the numbers 2.3 and 0.4 will give us an answer of 5.75. There exists a rule which states that when two similar numbers are divided only having different exponents, their exponents should be subtracted. The final answer to this item is therefore,
5.75 x 10¹¹
13 < 2t + 3 < 27
13<2t+3 2t+3<27
13-3<2t 2t<27-3
10<2t 2t<24
10/2<t t<24/2
5<t t<12
5 < t < 12
