The mistake the classmate made was multiplying the exponents "10" and "3" together to make "30" without taking the "8" into account. The correct answer is 549755813888.
OK so my answer is from what you’ve just explained that means you multiply the six and the 114 is 684 so that means if you have to do that to 13 of them that means 684×13 is what your equation would be in the answer to 684×13 is 8892
