$$6^{30}$$
Using the quotient rule for exponents, which states that if you divide two powers or exponents with the same base, you just subtract the exponents. So we subtract the exponent of the denominator from the exponent of the numerator: $$6^{40-10}$$ Simplify by subtracting the powers: $$6^{30}$$
