WebTo write a decimal in expanded form, we need to break down each digit according to its place value. Start with the whole number portion, identifying the hundreds, tens, and ones places. Then, move on to the tenths, hundredths, and thousandths places. Keep in mind the order of operations when combining the expanded terms. Created by Sal Khan. WebJun 25, 2024 · This is about expression of given algebra in standard form making use of laws of indices. A) We are given; (7 × 10⁵) × (3 × 10²) Now according to the law of indices, when we want to multiply 2 numbers with same bases and different exponents, we retain the bases and add the exponents.

This is a cubic equation (the highest exponent is a cube, i.e. x 3), and is hard to solve, so let us graph it instead: The zero points are approximately: −1.1; 1.3; 2.9; And from the graph we can see the intervals where it is greater than (or equal to) zero: WebKey ideas "Scientific notation" is also called "standard form". We use powers of 10 to express very large or very small numbers in scientific notation. Multiplying by a positive power of 10 moves the decimal point to the right. Dividing by a positive power of 10 moves the decimal point to the left. Powers of 10 10 1 = 10 10 2 = 100 10 3 = 1000 rcw original will
