2.6%2A10%5E-3%2F%282%2A10%5E2%29=%282.6%2F2%29%2A%2810%5E-3%2F%2810%5E2%29%29
To divide exponential expression with the same base, subtract exponents.
x%5EM%2Fx%5EN=x%5E%28M-N%29
2.6%2A10%5E-3%2F%282%2A10%5E2%29=%282.6%2F2%29%2A%2810%5E-3%2F%2810%5E2%29%29
2.6%2A10%5E-3%2F%282%2A10%5E2%29=%281.3%29%2A%2810%5E%28-3-2%29%29
2.6%2A10%5E-3%2F%282%2A10%5E2%29=1.3%2A10%5E%28-5%29
