Then find the value.Step 1 Identify the base. The base is 4.Step 2 Identify the exponent. The exponent is 5.Step 3Write the base as many times 4 × 4 × 4 × 4 × 4as the exponent tells you. Placea multiplication symbol between the bases.Step 4 Multiply. So, 45= 1,024.Write as an expression using equal factors. Then find the value. 1. 34 2. 26 3. 43 4. 53 5. 104 6. 85 7. 114 8. 152 9. 10710. 254ExponentsOBJECTIVE Write and evaluate expressions involving exponents.LESSON 49CC.6.EE.1You should have one less multiplication symbol than the value of the exponent.4 × 4 × 4 × 4 × 4 = 1,0243 × 3 × 3 × 3; 814 × 4 × 4; 6410 × 10 × 10 × 10; 10,00011 × 11 × 11 × 11; 14,64110 × 10 × 10 × 10 × 10 × 10 ×2 × 2 × 2 × 2 × 2 × 2; 64
