Math help plz!!!There is an average of 3.5×10^−2 kilograms of dissolved salt in each liter of seawater. The South China Sea contains approximately ​ 9.88×10^18 ​ liters of seawater. About how many kilograms of dissolved salt are in the South China Sea? Enter your answer, in scientific notation, in the boxes.__ x 10^__ kgPlease help and thank you!

Answer:3.458 × 10¹⁷Explanation:We multiply the amount of salt per liter, 3.5×10⁻², by the amount of sea water in the South China Sea, 9.88×10¹⁸:(3.5×10⁻²)(9.88×10¹⁸)Multiplication is commutative; this means we can switch around the numbers we are multiplying:(3.5×9.88)(10⁻²×10¹⁸)Multiplying the numbers in the first set of parentheses, we have 34.58.To multiply the powers of 10, we use the product property; it states that if we multiply powers that have the same base, we add their exponents:10⁻²×10¹⁸ = 10⁻²⁺¹⁸ = 10¹⁶This gives us 34.58 × 10¹⁶.  In scientific notation, the decimal must be behind the first non-zero digit; this gives us 3.458.  When we move the decimal again, we add 1 to the exponent; this gives us 3.458 × 10¹⁷
