Q). Write 2(to the power of 25) x 5 (to the power of 27) in standard form.

Is there a way to do this more easily without a calculator?

It's a 3 mark question so should be done in 3 minutes or so I assume?

I understand the answer is 2.5x10(to the power of 26) but edexcels revision booklet doesn't give any information on how to even approach this.

Thanks!
